To all whom it may concern:

citizenof the United States, residing at the city of Topeka, `inthe county of Shawnee and State of Kansas, have invented certain' new and useful Improvements in Machmes for Making Paper Boxes, (Case-13,) of which thefollowing is a specification.

The present invention relates to machines for making paper boxes and more particu# larly to machinesY designed' forproducing the body or receptacle portion of a carton, the primary object being vto, provide a machine: ofthe character described which is adapted for producing a receptacle, which may serve the .purpose of either the body portiony or the carton.

4Another object of thevpresentinvention resides in the provision of a machine which simultaneouslyfeeds the blank formingY the wall of the box andA the wrapper which is secured thereto by means of an adhesive, the blank being projected by a rotating boxforming mandrel and the adhesive strips being subsequently moved into engagement with the blank, and, in conjunction with the novel cam-operated mechanism, bendsthe blank to form the -walls of a rectangular receptacle while the blank is being fed forwardly, the adhesive wrapper atthe same l time being wrapped upon the stiff' blank und strip upon about the same VApletely folded around the mandrel, whereby" the adhesive strip is in reality severed transthe adhesive wrapper 'to overlap the forward end of same by further movement ofthe mandrel.

A vfurther Yobject `of the. present invention til the rear end of the wrapper overlaps the forward end thereof before the' folded blank is moved`to receive the bottom of the box.

Another object of thev present invention is to provide novel means 'for insuring the pasting of thel forward'endof the adhesive the blank sothat the forward end of the adhesive wrapper is flat and smooth upon the`blank before the rear end thereof overlaps same.

`Anotherobject of the to provide novel means for severlng the adhesive strip just-.lpriorito the pro]ect1on of the next blank -of cardboard and, also, at

time the blank has been compresent invention is versely at suchpointthat the rear end fV will be caused slightly is to provide novel means for holding the adhesive strip in engagement with the stiff blankand at the same time holding the blank- 1n vengagement -with the mandrel, so as to cause the blank to bend around the mandrel and, also, to press the adhesive wrapper into engagement with the blank, whereby the adhesive wrapper will be completely pasted upon the blank .before the .latter is moved to receive the bottomof the' box.

A still further object of the present invention is to'provide novel means'for folding and ing in the u perprojecting. edge of the adhesive strip a er the adhesive wrapper has been pasted upon theLfolded blank and while thei latter is still upon themandrel, so'that, when the foldedfblank is 4ejected `from themandr'el so as to receivethe bot- `tom of the box, such folded or tucked .in portion of the adhesive "wrapper will be ressed` 'against'ftheinnerface ofthe folde blank so .as tosadhere thereto.

`A stillffurther object yof thepresent invention is: to provide novelmeansfor holdfing; the revolubleA mandrel temporarily stationary' in` atposition in which the faces of same register in the same, planes with the corresponding .faces .f :a reciprocatory block, whereby the end 0f the block will enterand support'the'folded blank, when the latter is ejected'from the mandrel.

A still l further object of the, present invention is to.v provide novel means for feeding the bottom of the box to a position in engagement with the reciprocatory block 'just prior tothe ejection ofthe lfolded blank `from the mandrehso thatthe bottom of the boxwill enterthefolded blank. f

A still further object of the presentY invention is toA provide' novel means for holding the bottom of the box in engagementL with the endf the'reciprocatory block while theifoldedzblank .is helingr ejected from the mandrel, so that-same Will enter said blank.

Astil'l'further object of' the.present invention isvto" vprovide novel meansfor folding lthe"lowerprojecting.edge f the adhesive wrapper against the' lowerface of the bottom of. the box while thel folded blank is supporteduponthe reciprocatory block, so that such folded portion of the adhesive wrapper will vadhere to thebottom of the box and thereby hold same in lace.

A still further object vofet e present invention istoprovide novelmeans foi-,reciprocating the block so that. the latter will' travel away from the mandrel while the Y charging the ejected box from the machine so as to prevent same frombecoming entangled in the moving parts of the machine. With the foregoing and other objects in view, the present invention consists of the novel features of construction and arrangement A yof parts hereinafter described and pointed out in the claims.

In taking up the case for detailedA description, the same will be considered under six headings, namelythe frame, which includes the drive shaft, operating cams, the blank-containing hopper, and bottom containing hopper; the blank-and-adhesivepaper-feeding mechanism; the blank-andadhesive-paper-guide-and-forming mechanism; the paper-cutting mechanism; the bottom-feedingand-finishing mechanism; and the box-ejecting mechanism.

The frame- The main frame or support 1 of the machine has mounted thereupon the four shaft-carrying supports or journals 2, 3, 4. and 5, which are provided with two vertically alined journals, respectively, whereby the main shaft 6 is prbperly supported in the lower journals of the four supports 2, 3, 4, and 5, such shaft being disposed longitudinally of the machine and operated through any well known means preferably connected to the left end thereof as viewed in Fig. 2.

In order to operate the several mechanisms, mounted upon the driveshaft 6 are .the cams 7, 8, 9, 10, 11, 12, 13,14, and 15, eccentric 16, and

disk 'or plate 17, so that all such mechanisms are operated directly from the main drive shaft. Mounted upon the drive shaft 6 Aso as to rotate therewith 1s a large gear or pinion 18, which meshes with a smaller gear or pinion 19 rigidly shaft 20, which is revolubly supported in the upper journals of the two supports 2 and 3 and has the secured to the inner end thereof the comi so vas to rotate therewith, the detailed delatter is being rotated through three-fourths of a revolutlon by the drive shaftv 6, and will -remain at rest while the drive shaft is rotating the pinion 18 through the remainder or last Aquarter of theprevolution.

The diameter of the pinion 18 is of such.

size relatively to the diameter of the gear 19 that each time the drive shaft 6 is rotated through a complete revolution, the gear teeth on pinion -18 cause the gear 19 theA counter shaft 20 to rotate through substantially two complete revolutions. In order to prevent rotary movement of the counter shaft 20 while the drive shaft6 is rotating through the last quarter of a complete revolution, z'. e. while the pinion `18 is rotating with its teeth out'of engagement'with the gear 19,. the gear 19 is provided with an extension 2l or the like lhav-v ing an arcuated cut-away portion 22 in its periphery, which cut-away portion -22 is so arranged that, when the gear teeth of pinion 18 pass out of engagement with the gear 19, the cut-away portion 22 will occupy a position concentric with the shaft 6 so as to allow the arcuated projection or plate 23 borne by cam 7 to enter same, .said projec- 'tion or plate 23 being of such length 'and arranged so that samewill travel through the cut-away portion 22 only while the gear teeth of the pinion 18 are out of engagement with the .gear 19, thereby preventing the counter shaft 20 temporarily from rotating, but as soon as the gear teeth of pinion 18 again move into engagement with gear'19,

the arcuated projection or plate 23 passes out of the arcuated cut-away portion 22 and thereby permits the pinion 18 to rotate thegear 19. In order to cause the gear teeth of pinion 18 to mesh in properrelation with the gear teeth of gear 19, the pinion 18 is provided Ywith a lug 24, whichis adapted to strike a lug 25 on gear 19 at the time the gear teeth of'pinion 18 are about to engage the gear teeth. of gearv 19, whereby the gear 19 will be rotated so as to bring' the gear teeth thereon in properrelation to the gear .teeth of pinion 18, with the result "of causing the gear teeth of pinion18 to mesh properly with the gear 19. ln order' to prevent longitudinal movement of the, counter shaft 20 in the upper 'journals of supports 2 and 3, the gear 19 is so mounted upon the shaft 2() that its hub is in close proximity to one side of the support 2, and a collar 26, also, mounted on said shaft 4is placed in close proximity to the other side of said support.

pull

hopper or chute. like, by means of which'one end' of theltlexi Mounted upon the main frame 1 to the rear of the drive shaft 6 and substantially centrally of the machine, is the supporting plate 27, to which is connected and carried the base plate 28, on which at its forward end adjacent tothe mandrel M is carried the blank-containing hopper 29. `Said hopper is preferablyv disposed at substantially a rightangle to the axis of rotation of mandrel M, and contains the blanks 30 of cardboard or the like, said blanks being preferably scored at the points where same are to be folded and being cut to the proper length and so `positioned within the hopper that same can be fed one at a time from the bottom thereof, a weight 31, which rests `upon the blanks 30, assistingin such feeding as will presently appear. If desired, the ends ofeach blank 30 may be tapered' so that -when same overlap, the sides and ends of the complete box will khave a substantially uniform thickness.

The bottom-containing 32'is, also, located in the rear of the drive shaft 6 and is su ported upon standard 33 or a plurality o such standards mounted upon the main frame 1. Said hopper or chute' 32 is preferably disposed substantially parallel to the axis of rotation of the mandrel M, and contains the bottoms 34 of cardboard or the like, said bottoms being preferably cut to the proper size and shape to it between 'the side and end walls of the box and being sopositioned within the hopper or chute 32 that same can be fed one at a time from one end thereof. In order to assist in such feeding'of the hopper or chute 32, a block 35 is provided which is capable of sliding in said hopper or chute and being connected to a weight 36 or the like Iby means of a flexible member 37, which passes` over a pulley 3 8 or a plurality of such pulleys rotatably attached to said hopper o-r chute, and by this arrangement, the

of the weight 36 upon the lexiblemember 37 causes thev block 35 to'move the bothopper or chute toms 34 toward :the discharge end of said A screweye 39 or the ble member 37 is attached tothe block 35, protrudes through a slot 40,'which extends chute 32,- so as to allow the block 35 to slide longitudinally in said hopper or chute,

and, also, prevent said block from workingy l5,

out `of said ,hopper or chute.

longitudinally in one side of the. hopper or The bla/li'offdndf adhesvepaperfeeding mechanism-Ems mechanism comprises, es-

sentially, the eccentric-rod 41 one end of which is attached to the eccentric-strap 42,

which encircles the eccentric 16, and the other end of which is adjustably connected by means of a bolt or pin 43 in-an elongated slot 44. in the arm 45, which is rigidly mounted on the rock-shaft. 46, the latter be ing preferablydisposed substantially parallel to the drive shaft 6 and being journaled in the supporting plate 27 and, also, in a support 47 mounted upon the frame 1. By this arrangement, when the drive shaft is rotated, the eccentric 16 causes the arm 45 to oscillate forwardly and rearwardly of the machine through the medium of the eccentric-strap 42 and the eccentric-rod 41 and thereby rocks the sh'aft 46. Mounted upon the shaft 46 so as to rock therewith is an arm 48 having one end of thereto, the other endof such link being pivotally attached at 51 to a lug 52 borne by the blankffeeding plate 53. This plate 5 3 is mounted for. longitudinal reciprocation between the guides of the base plate 28 of the blank hopper 29 and is provided with the reduced blank-engaging end 54 having an abrupt shouldered portion 55 upon the upper face thereof, so that upon the forward movement of the plate 53 the lower blank within the hopper l29will assume the position as shown in Fig. 17 and be propelled through the aperture 56 at the lower end ofthe hopper 29 and below' thev springdepressed gate .57, which has its lower end chamfered as at 58 to permit the passage of c the blank, when the latter is propelled forv'or the like'being wardly out of the hopper toward the mandrel M- by the plate 53, but which, upon the retraction of the plate 53, will snap down- -wardly and close the'aperture 56, so as to prevent the l passage of another blank, until .the plate 53 has,v assumed the dotted line lposition as depicted in Fig. 17. The blanks 30 -are held in vertical alinement in engagement with one of the side walls of the hopper 29 by means vof a flat spring 59 or the like, or a pluralityof such. springs, a flat spring 60 arranged to guide each blank 30 when the latter is fed through the aperturev 56.

The strip of paper 61 having an adhesive applied uponione side thereof (preferably thel upper side) extends from any suitable source and passes over a plate or board 62, which is supported upon a bracket 63 or the like mounted upon the main frame 1,1and then over ,a guide, 64 located directly below the hOPPer 29 and secured tothe supporting plate 27 by any vsuitable means. The for- I ward-end of the adhesive. strip 61 projects beyond the forward endof the guide 64 and a roller'65, which is ro.

normally rests upon tatably attached'to the rear end of a lever 66 by means of a pin 67 or the like, said lever being rigidly vmounted on a shaft 68, which is journaled in supports 69 mounted upon the main frame 1. A spring 70, which is attached to the forward end of lever 66, pulls same downwardly and thereby raises the rear end of saidlever, so as to cause the roller to raise the forward -end of adhesive strip 61 for the purpose about 'to be dea link 49 pivoted at- 50 gripping devicecarried by the the member 74, and, when the adhesive stri scribed, such movement' of said lever 66 being controlled by the cam 11 through the instrumentality ofthe arm 71 borne by shaft 68 and having `a roller 72 rotatably attached thereto by means of a pin 73 or the like, said roller 72 being held at all times in engage-- ment with the cam 11 by means ofthe spring 70. Th cam 1l is positioned upon thedrive shaft 6 so as to permit of this raising of the roller 65 by the pull of spring 70 at the same `time lthe blank 30 has been fed forwardly out of the hopper 29 sufliciently to allow the forward end thereof to mandrel M, as will be presently described, whereby said roller 65 raises the forward end of the adhesive strip 61- into engagement with the blank 30, as depicted in Fig. 17 and holds said strip into engagement with said blank until sameadheres to the latter, aft-er which the cam 11 will rock the shaft 68 counterclockwise, Fig. 17, throughthe medium'of the lever 7l and thereby cause the lever 66 to lower the roller 65, and the blank 30 will e draw the adhesive strip 61 forwardly there# with until thelatter is severed in the manner hereinafter described.

A- member 74, which is located in front of the hopper 29 and directly above the roller 65, is secured firmly to a bracket 75 or a plurality of such brackets by screws 76, the bracket being secured to the base plate 28 adjacent to the forward end thereof by screws 77 or other suit-able means. Said ymember 74 is disposed at a'slightly higher elevation than the 29 so that, when the blank 30 is fed forwardlythroughthe aperture as hereinabove described, saidl blank will passunderneath 61 is raised into engagement with the blank 30, said member will coact with the roller 65, so as to press the adhesive strip v61 intoengagement" with the blank 30'wi`th lsutiicient pressure to causesaid strip to adhere to said blank. The lower surface of member 74 is grooved transversely to form ribs 78, which'provide the proper contact surface forthe blank 30 and strip 61 during the projection thereof to the mandrel M, and at the same time not tohave face to retain any too great amount f the adhesive from the strip 61 that might interfere with the feeding of the blank and strip to said mandrel. For the same reason, the roller 65 is preferably corrugated longitudinally.

The blank and paper fowmlng mechanism- The mandrel M is preferably formed with. a rectangular cross-sectional configuration, and consists of the main or initial `forming block 79 and the auxiliary o'r final lforming block 80, which may be formed integrally with said main forming block or secured thereto by any suitable means, there aperture 56 in the hopper suilicient sur- -auxiliaryor nal cent the groove 81 being -a perimetrical groove 81 in said mandrel between said blocks for the purpose hereinafter described, and the edges of the forming block 80 adjabeing lpreferably rounded so as to allow the folded blank to pass readily over said block 80when said blank is ejected from the main forming block 7 9- as hereinafter described. Said mandrel is so positioned relative to the hopper 29 that, when a hopper toward said mandrel until same is caught by the blank-clamping lever 82 and folded against the flat faces of the main foi-min block 79, one ledge of said blank, prefera ly the particular edge that becomes the upper edge of be flush with the wall 83 ofthe groove 81. The blank-clamping lever 82 has somewhat the shape of a bell-crank, and is pivotally attached at 84 to a lug 85 or a plurality of suchlugs borne by the mandrel M, the larm 86 of said lever being adapted to clamp the forward vend .of the blank 30- in a notch y87 in the main forming block 79,. and the arm 88 of said lever being'disposed in the path ,of movement of a hook 89 or the like vborne by member 90, which is spl'ined /upon the shaft 20 so that samecan be reciprocated longitudinally on said shaft. ln order to reciprocate the member 90 upon the shaft 20, Said member is proi'zided with an annular reduced portion 91, which is revolubly fitted in lan opening in a plate 92, said plate being preferably connected to a pair of rods 93, which rods are mounted for longitudinal movement in apertures in the supports 2 and 3. By this arrangement, when the rods 98 are reciprocated, the plate 92 travels therewith and causes the member 90 to reciprocate upon the shaft 20. Said rods 93 extend through openings in, 'a block 94,l

and are secured to said block by any suitable means, said block being sl-idably mounted upon4 the shaft 20 and having a roller 95 rotatably attached thereto, which roller 'projects into a cam-slot 96 in cam 7 A spring 97 exerts its pressure against one side of the block 94 and` thereby holds the roller 95 in engagement with one side of the cam-slot 96. The cam-slot 96 is so arranged that dur y each rest period of the shaft 20, same Areciprocates the block 94 upon'the shaft 20.V

ing

and thereby causes the member 90 to move toward and away from the mandrel M, and

the hook 89 to move away from the end of the arm 88 of the lever 82, whereupon the spring 98 rocks the llever 82 clockwise to the position depicted in Fig. 2, thereby moving the clampm arm 86 of said lever out of the n otc h 87 in the main lforming block 79. While the lever 82 occupies such position` the blank 30 is fed forwardly out of the hopper 29 so as to move the forward end thereof to a position between the clamping 'karmti of the lever blank is fed forwardly out of said` the completed box, vwill 82 and the notch 87 in 79, at which time the been moved away from the forming block member 90 will have 89 into'engagement with the end of the arm 88 of lever 82, thereby rocking the lever -82 counter-clockwise, Fig. 2, with the result of causing the arm 86 of said lever to clamp the forward end of the blank 30 in the notch 87 in, the forming block 79, as best seen in Fig. 17. This clamping of the forward end -of the jblank 30 in the notch 87 in block 79 takes place just rior to the completion of the rest period o mandrel M, so that when the latter is rotated -the blank 30 will be drawn forwardly by same. The end of the end ofthe arm 88 of the lever 82, while the mandrel Mis rotated, and thereby causes ,the clamping arm 86 to hold the forward end'of the blank 30 in the notch 87 in the block 79 until the adhesive strip 61 covering same is shifted from the mandrel M during the next rest period of the latter. In order topermit the end of the hook 89 to iride readily upon the arm 88 of lever 82, when the member 90 moves the hook`89 away-from the mandrel M, the ends of said hook and arm are beveled asbest seen. in Fig. 18. As hereinabove described, the mandrel M rotates with the -shaft 20'and, as the gear 19 is of such size relative to the pinion will be rotated two complete revolutions for each complete revolution of the drive shaft 6 the mandrel M will, in. consequence, be rol-- ment with the main forming block 79 of the mandrelM and at the same time press the adhesive strip 61 in engagement with the 'blank 30 so as to fold said blank and said .strip around said forming block 79 while Athe mandrel M is being rotated, a roller- 99 is provided, same being lplreferably located funderneath the mandrel and being revo- ;lubly attached to the prongs 100 of the forked end of a lever 101 by means of a bolt or pin 102, saidy leverA being rigidly mounted upon a shaft 103, which is Journaled 1n supp orts 69. A spring 104, which is connected tothe other end of the lever 101, exerts a tension to hold the roller 99 up to and in engagement with the main forming block 79 of mandrel M, but in order to impart the `desired movement to the roller 99, the arm '105, which is, also, rigidly vmounted on the vshaft 103, has a roller 106 rotatably at tached thereto by means of a pin 107 or the like, said roller 106 being held in engagement with the cam 10 by the'pull of spring 104 so that said cam will actuate the roller the mandrel M sufficiently to bringthe hook 18 that said shaft 20' In order to' hold the blank 30 in engage-l hook 89 remains 1n engagement with the f folded blank with the v 299 through the medium of-arm 105, shaft -102, and lever 101 during the rotation of the mandrel M that while drive shaft 6. The cam 10 is so positioned .upon the drive shaft 6 with respect to the forwardly out of the hopper 29 by the blankfeeding plate 53 until the forward end thereoflis clamped in the notch 87 in the main forming block 79 of mandrel M by the arm 86 of the lever. 82, the cam 10 holds the lever 101 in the position depicted in Fig. 17 through the medium of the arm 105 and the shaft 103 and thereby holds the roller 99 out of engagement with the adhesive strip 6.6.l The roller 99 is held in theposition just described until the blank 30 causes the forward end of the adhesive strip 61 to pass over the roller 99, after which the cam 10 allows the roller-99 to be raised into engagement with the adhesive stri 61 by the pull of spring '104, whereby saidp roller not only presses the adhesive strip 61 into engagement with lthe blank 30, so as to cause same to adhere thereto, but, also, holds the blank 30 in .engagement with themain forming block 79 of the mandrel M, with the result of bending or folding said blank and strip completely around said block. When thus foldedaround the forming block 79 of the mandrelM, the rear end of-the blank 30 will .overlap the forward end thereof, and dpr-l ing such folding operation, the 4adhesive strip 61 will be severed` in the mannerherelnafter described, so that the rear end there- Y of will overlap the forward end of same ,upon the folded blank, thereby to cover the latter com letely. After the rear end ofthe severed a hesivestrip 61 overlaps the forward end thereof, the cam 10 restores the roller 99 to the position depicted in Fig. 17 v and4 retains same in such position unt1l the next blank 30`is being drawn forwardly bythe mandrel M as herelnabove described.

By this means, the blank 30 is folded into a rectangular shape against the dat faces of the main forming block 79 of the mandrel M, while the latter is being rotated, and is held in such shape by the adhesive wrapper 61 after the pressureI of the roller 99 is 1 eleased from said wrapper.. If desired, the roller 99 may for thesame reason that roller 65 is corrugated, as hereinabove described. When the adhesive strip 61 is raised into engagement with the blank 30 bythe roller 65, as hereinabove described, it may happen that the extreme forward end 108 of said strip will not be pressed'into engagement with said blank, but will hang loosely from the blank as depicted in Figs. 17 and 18. In order to in sure the pressing of this loose end 108 of the strip 61 1nto engagement with the blank 30 so that same will adhere to and lie fiat upon y said blank before the rear end of said strip in supports 2 overlaps same, the following mechanism is provided. A shaft 109, which is journaled and 3, extends beyond the t-he blank A30 is' fed 'tation of an arcuated y brush be corrugated longitudinally' .hesive strip which is the blank 30 is utilized, so that, when thev support '3 and has a brush-holder 110 se preferably .disposed approximately radially f to the shaft 109 and being located in front of and adjacent to the main forming-block 79 of the mandrel M. A spring V1412 tends to rotate the shaft 109 counter-clockwise, Fig. 10, and thereby holds the arm 113 borne by said shaft normally in engagement with one of the rods 93, with the result that the end of said arm extends into the path of romember or flange 114 borne by cam 7. When the arm 113 Aoccupies the positionjust described, the brush 111 Vinclines upwardly as depicted in Fig. 5, so as to beout of the path of rotation of the mandrel M. During each rest eriod of the mandrel M, the arcuated mem er or flange 114 borne by cam 7 engages the arm 113 borne' by shaft- 109 and thereby rocks said; shaft clockwise, Fig. 10, or counter-clock-g wise, Fig. 5, with the result of moving the 111 downwardly from' the position de-l picted in Fig.` 5 to the position depicted in Fig. 17, and causing said brush to engage the adjacent face of the main forming blpck 79 of the mandrel -M, which at this particular stage of the operation occupies the posit-ion to receive the forward end of the blank 30 in the notch 87 in the lower -faceof said block. After the brush 111 has been moved to the position depicted in Fig. 17 the end of the arm 113 rests upon the arcuated member or flange 114 borne by cam 7 and thereby holds said brush in such position until the mandrel M moves the blank 30 and adhesive strip 61 forwardly sufiiciently to bring the loose end 108. of the ad-` position directly behind of the shaft 109, as depicted in Fig. 18, at which time the member or ange 114 borne by cam 7 passes out of engagement with the end of arm 113, wherehesive strip 61 to a the axis o rotation Vupon the spring 112 rocks the shaft 109 suddenly clockwise, Fig. 17, and thereby causes the brush 111 to wipe or press the loose end 108 of the adhesive strip 61 lliatly upon the blank 30, so as to cause same to adhere thereto.

In order that the'adhesive strip 61 may be folded in so as to cover both edges of the blank 30, when the latter is folded, an adi relatively wider than blank andadhesive strip are foldedI around the forming block 7 9- of the mandrel M, said strip will extend beyond both ledges of the` i l blank and one edge of -said strip will project over the perimetrical groove 81 in said mandrel' in order to wall 83 of said groove by the folding blade 115 in the manner now to be described. This folding blade 115 is carried by the lever 116 which is rigidly mounted'on the rock-shaft be folded against thev V edge of the adhesive strip 61 projecting over in the mandrel M has been folded in against Agroove 81,with the result of creasing or foldvstrip upon the next folded blank is ready the folded blank with the adhesive wrapper a pair of -held flatly in engagement with said faces by means of springs 125, respectively, which 117 the latter being journaled in supports l 118 mountedA upon the main frame 1 spring 119 exerts a tension to pull the blade 115 toward the mandrel M, but such movement of said blade is controlled by the cam 8 through the medium of arm 120, the latter being rigidly mounted on shaft 117 and having a roller 121 rotatably attached at 122 thereto, which roller is held in engagement with the cam 8 by the pull of spring 119. The cam 8 is provided with a plurality of cam notches123, which are adapted to permit four movements of the upper free end of the lever 116 toward and away from the mandrel M, while the latter is being rotated through the second complete revolution. These movements of lever 116 are so timed that each time a flat face of the mandrel M is presented to the blade .115, the latter will' be moved into and withdrawn from the ing the adhesive strip inwardly against the wall 83 of said groove as depicted in Fig. 23, so that', when the mandrel has been rotated through the seco d complete revoluto pass or j ovel the auxiliary 'wrapper which tion, the four faces of same will have been presented to the folding blade 115 and the the groove 81 in the mandrel will have been turned in against the wall 83 of said groove, after which the cam 8 will move the blade 115 to the position depicted in Fig. 11 through the medium of arm 120, shaft 117, and lever 116, and, thereafter, will hold said blade in such-position until the adhesive to be folded so as to cover the upper edge of the box, as just described.

After the edge of the adhesive strip 61 that projects normally over the groove 81l the wall 83 of. said groove, the mandrel M ceases rotating immediately and stops in a position 1n which the two largest flat faces of the mandrel are substantially perpendicular to the main frame 1 of the machine, and during this rest period of said mandrel thereon is ejected from same by the following means. Connected to the member 90 is ejecting plates 124, which plates. are adapted to reciprocate with the member 90 and thereby slide alongthe two longest flat faces of the mandrel M, the. same being are, also, secured to said member. While the blank 30 and theadhesive strip 61 are being folded around the main forming block 79 of the mandrel M, as hereinabove described,

depicted in Fig. 18, so that said plates are out of engagement with the blank 30, so as to allow the blank -to 'be folded upon the forming block` 79. Said ejecting plates 124 are relatively thin' so that, when same are moved toward the folded blank 30 upon the forming block 79, the ends will pass underneath the edge of the adhesive strip that projects from the left-hand edge of the folded blank as viewed in Fig. 18, and will thereby engage `the edge of said blank. During each rest period of the mandrel M, the member' 90 is moved toward said mandrel as hereinabove described, and, in turn, moves toward the right Fig. 1, whereby the ends of said pla-tes engage 'the left-hand edge of the folded blank 30 upon the main forming block 7 9 of the mandrel M and thereby not only eject the folded blank and its adhesive wrapper from said block 79 but cause same slide over the auxiliary forming block 80 until ejected from the latter to receive a bottom 34 in the manner hereinafter described'. Whenthe folded blank with the adhesive wrapper thereon is caused to pass forming block 8() of the mandrel M, vthe edge of the adhesive was previously folded in against the wall 83 of the groove 8.1 in vsaid mandrel tis tucked or folded in farther by the auxiliary forming block 80 until the same is pressed against the inner faces of the folded blank, before the folded blank is`ejected from said block 80. After the folded blank with the adhesive wrapper thereon is ejected from the final or auxiliary forming block 80, the member 90 is moved away `from the mandrel M, with the result of. moving the ejecting'plates 124 toward the left Fig. 1 until the latter are restored to their normal positions so as to allow the next blank 30 and its adhesive strip 61 to be' folded upon the main forming block 79 of said mandrel.

From the foregoing, it will be apparent that after the blank-feeding mechanism is operated and the adhesive strip 61 is raised into engagement withlthe blank`30, the mandrel YM being in theI position, as clearly shown in Fig. 17, and t e clamping` arm 86 of lever 82, at this particular time, being held in the position depicted in Fig. 2, so that the forward end of the blank will be clamped in the notch 87 in the main forming block 79 of the mandrel M,'as illustrated in.

Fig. 17 a rotary action is imparted to the mandrel, thus twirling the blank and adhesive strip thereupon while the,cam.10, which operates the forming roller 99 through the medium of arm 105, shaft 103, and lever 101,

raises said roller and thereby causes same not only to press the adhesive strip 'into engagement w1V the blank into engagement with the main form# ing'block 79. of the mandrel, with the result 'th the blank, but, also, to press of rolling and properly folding the blankand adhesive stri about the forming block 7 9 while the man rel is rotating'through the complete revolution, severed 1n the manner first complete revolution and approximately one-fourth of thel second revolution.

About the time the mandrel M makesthe the adhesive strip is hereinafter described, and, during the second complete revolution of the mandrel M, the blank is completely covered with the adhesive strip, and the cam 8 operates the folding blade 115 through the medium of arm 120, shaft 117, and lever 116, with the result of folding in the-edge-of the adhesive strip that previously projected over the groove 81. h

' After the mandrel M completes the second complete revolution, same remains at rest while the main drive shaft 6 rotates through approximately one-fourth of a revolutionfduririg which time, the cam slot 96 in cam 7 causes the member 90 to move toward and away from the mandrel, with the result v that, while the member 90 'is moved toward the mandrel, the ejecting plates 124 push against the left-hand edge of the folded blank upon the-main forming block 79, as viewed in Fig. 2, thereby moving the folded blank toward the right until same withthe adhesivey wrapper thereon passes over the auxiliary formingblock 80 of the mandrel, so as to have the folded-in -edge of the adhesive wrapper tucked in farther to adhere to the inner faces of the folded blank, and finally leaves the auxiliary forming block 80 in order to receive the bottom 34 of the box in the manner'hereinafter described. The movement of the member 90 toward the mandrel M causes the hook 89 to move out of engagement with the e'nd of the arm 88 of lever82, whereby the clamping arm 86 of said lever releases its pressure upon the end of the blank 30 in the notch 87 in the forming block 79, so as to permit the easy' withdrawal of the end of. the blank from said notch when the folded blank is the otherend of said t' th lte27. A 65,1n epa ejected from said block; While the member 90 moves away from the mandrel, same restores the hook 89 and the ejecting plates 124 to their initial positions, whereby the hook 89 again engages the arm 88 of lever 82, so as to cause the clamping arm 86 of said lever to clamp the forward end of the next blank 30.

The paper-cutting mechanism-In order to sever the adhesive strip at the proper time, that is, after a strip 61 of such length that the rear end thereof will overlap the forward end of same when wound upon the folded blank upon the main forming block 79 of the mandrel M as hereinabove described, the following mechanism is provided: A standard 126 is mounted upon the main frame 1, of the machine, and has one end Yof a rock-shaft 127 journaled therein. shaft being journaled lever 128 is rigidly mounted on shaft 127 and has a blade 129 the cutting edge 131 of the blade 129 to cooperate in shearing relation with the shearing edge 132 borne by the member 74. Arm 133 has aroller 134 rotatably attached at 135 thereto, said roller being held in engagement with the cam 9 by means of the spring 130. The cam 9 is provided with a periphery which, when the'adhesive strip 61 is being drawn e forwardly by the blank 30 as hereinabove described, holds the cutting edge 131 of the .blade 129 below the'path of travel of the adhesive strip 61 through the intermediation of' the arm 133, shaft 127, and lever 128, as clearly illustrated in Fig, 17. When the proper length of adhesive st'rip 61 suliicient to cover the folded blank, in the manner hereinabove describedV has? been drawn forwardly by the roller 134 rides olf a whereupon the pull of spring 130 rocks the! shaft 127 suddenly "in a counter-clockwise@ direction, Fig. 17, whereby the forward end of the lever 128 raisesthe blade 129 quickly, with the result that the cutting edge .131 -of blank, thei said blade presses into engagement with the y shearing edge 132 on member 74.and thereby severs same at a point in -front of the roller 65, so that the forward end ofthe remaining strip will rest upon said roller afterl the cutting operation, the rear end of the blank which is being folded upon the main forming block 79 of the mandrel M being, at this particular time, drawn beyond the path of movement of the cutting edge 131 of blade 129 so that only the adhesive strip 61' will be cut thereby. After the-cutting"opration takes place as just described, the cam E) lowers the cutting edge 131 of the blade 129 to its normal position so as to allow the nextl blank 30 to feeding plate 53 as hereinabove described.

The bottom-feeding-and-)nshing mechanism-The bottoms 34 occupy 'an upright position in the hopper or cnute 32 and are fed one at a time from the discharge end thereof by means of a feeding plate 137 whichl is mounted for recprocation in. a guide plate 138, said guide plate being secured to the dischargeend of said hopper or chute by screws 139 or other suitable means and being'supported upon the supporting plate 27. Mounted upon a rockshaft 140 so as to rock therewith is an arm 141 having one end of a link 142 pivotally attached at 143 thereto, the other end of-said link being pivoted at 144 to the bottomfeeding plate 137, so as to cause same to reciprocate when the shaft 140 is rocked, said shaft being journaled in the supporting plate 27, and, also, in support 47. A lever 145, Awhich is rigidly mounted on shaft 140,

shoulder 136 on cam 9,3' Y

be fed forwardly by the blankvided with a reduced .bottom-engaging endA 149 having an abruptshoulder 150 upon the face thereof that is adjacent the' discharge end of the hopper or chute 32, so that upon the forward movement of the plate 137 the 'shoulder 150 on the reduced end 149 of said plate will engage the first bottom 34' in the discharge end of thehopper or chute 32 and will move said bottoln'forwadly in an upright position out of the discharge end of said' hopper or chute, as illustrated in Fig. 20, a spring'l 151 or' other suitable. device being arranged so as to hold the bottom 34 in engagement with the reduced end 149 of said plate 137 n while said bottom is being propelledl from the discharge end of said hopper'. or chute. The bottom-feeding plate 137 is so positioned upon the .machine that, when the 'former is moved forwardly, the reduced forward end 149 thereofwill pass between the end of the mandrel M and the ed of the finishing-block B borne by the 'inner end of the bar 152, which is mounted for longitudinal reciprocation `in the supports 4 and 5, and in this way will move the bottom 34 to a position between the mandrel M and the block B, for the purpose hereinafter described. f

- The block Bl is formed with substantially the same .size and the same shape in crosssectional configuration as the mandrel M- and is disposed in axial allinement with the mandrel so that, during each rest period of the mandrel, the faces of the latter will register' in the same planes with the corresponding faces of the block B, respectively. A' spring 1'53, which may be attached'to the outer end of the bar 152 and, also, either to the' support 4 or support 5, exerts a tension' so as to move the barl 152l toward the left,

Figs. 1 and 2, and thereby move the block B vto toward the mandrel M'. A' member 154, which is adjustably mounted upon the bar -152 and fastened thereto by means of a setscrew 155 or the like, has a roller 15G rotatably attached thereto, which roller is held in engagement with the cam 15 by the pull of spring 153, Aand is reciprocatively mounted upon a rod 157, or a plurality of such rods, said rod or `rods connecting and being supported by the supports 3 and 4. The cam 15 affords a means not only for limiting the movement of the bar 152 toward the left,

Figs. 1 and 2, so that a space is left at all times between the end of thev block B and the end of the mandrel M, in oider to allow the bottom-engaging end 149 of the bottom feeding plate 137 to p'ass therebetween, but, also, for moving the bar 152 toward the right so as to move the block B away from the mandrel, and is so positioned upon the drive shaft 6 that, during each rest period of the mandrel M, said cam allows the block B tooccpy a position of est ne'ar the mandrel M, but, while the mandrel is being rotated the cam 15 causes the bar 152 to recipocate and thereby move the block B away from and toward the mandrel before the next rest period of the latter, for the purpose hereinafter described.

.The operation of feeding the bottom 34 fr'om thehopper or chute 32 as hereinabove described is timed to take place when the block B is near the mandrel M, z'. e., when the block B occupies the position of rest at the end of its travel toward the left, Figs. 1 and 2, so that the bottom-feeding plate 137 will move the bottom 34 to its proper position between the end of the mandrel M and the end of the block B before the folded blank with an adhesive wrapper thereon is ejected from the mandrel as hereinabove described. The auxiliary forming block 8O of the mandrel M contains an opening 158, which is preferably located centrally of the I end face thereof. A button 159 is reciprocatively mounted in the opening 158 in the ,block 79 of the mandrel and a spring 160 Lpresses said button outwardly so that thev t shank of same protude's from the end face i of said block 79, an offset 161 in said open- 'ing being provided' 'to limit the outward Lmovements of said` button. The outer end of the shank of tle button 159 bears against.

vthe end face of the'blo'ck B when the 'latter is near' the mandrel M as clearly shown in Fig. 23, and is' preferablf;7 rounded so that, when the bottom-feeding'plate 137 moves the bottom 34 out of the hopper or chute 32 to its proper position between the end face of the mandrel M and the end face of the block B, the bottom 34 will readily pass between the rounded end of the button shank 1 and the end face of the block B. The forward end 149 of the bottom-feeding plate 137 is provided with an elongated notch 162 to allow the shank of the button 159 to enter same when the plate 137 is moved forwardly,l so that said plate 137 can travel forwardly suiiiciently to move the bottom 34 to such positionl intermediate the end of the' mandrel M and the end of the block B that the edges of said biot-tomwill register in substantially the same planes with the corresponding faces of the mandrel and block in order to'enter the folded blank with the wrappeithereon, when same is ejected from the mandrel. While the bottom-feeding v the bottom plate 137 is moving the bottom 34 'from the discharge end of the hopper or chute 32, the spring 151 holds the bottom 34 in an upright position in engagement with the end 149 of said plate until the bottom passes between the rounded end of the shank of the button 159 and the block B, after which the pressure of the spring 160 causes the button 159 to hold the bottom in an upright position in engagement with the fiat end face of the block B, as depicted in Fig. 24. After the bottom 34 has been moved position between the end ofthe mandrel M and the end of the block B as just described, the plate137 moves rearwardly and thereby leaves the bottom 34 in its proper position in engagement with the end face of the block B, then the ejecting plates 124 eject the folded blank and its wrapper from the mandrel and cause same to move toward the right, Fig. 24, thereby causing the folded blank with its wrapper thereon to slide upon the botto-m 34 and, also, upon the block B until the left-hand edge of the folded blank is substantially Hush with the outer face of 34, after which the ejecting pl-ates return to their normal position and thereby leave the folded blank upon the bottom 34 and the block B. Thus, the folded blank embraces the bottom 34 andthe block B, which, in turn, supports same until the completed box is linally ejected from the machine. After the folded blank is moved to its proper position uponthe bottom 34 and the block, B as hereinabove described, the edge of .the adhesive. wrapper that projects from the left-hand edge of the folded blank as viewed in Fig. 24, is folded against the outer face of the bottom 34 by means of the mechanism now to be described, so that the adhesive wrapper will connect the bottom with'the folded blank and thereby complete the box. This mechanism for folding v the projecting edge of the adhesive wrapper against the outer face of the bottom 34 comprises two pairs of folding blades, namely, the blades 163, which are adapted to fold the edge of the adhesive wrapper at the ends of the box against the outer face 'of the bottom, and the blades 164, which are adapted tofold the edge' of the adhesive wrapper at the sides ofthe box against the outer face of the bottom. The blades 163 are secured to the levers 165, respectively, by. an suitable means, each of which levers is pre erably in the form of a bell-crank. One of the levers 165 is pivoted at 166 to the guide 'plate 138, so that its blade-supporting arm 167 extends above the block B, and the other lever 165 is pivotally mounted at 168 in a bearing 169, so that its blade-supporting arm 170 extends belowthe block B, said bearing 169 being supported by the supporting plate 27 and secured thereto by any to its proper the folded blank in such the mandrel M so opposite'direction therefrom. A spring 175 v holds the blade-supporting arm 170 of the lower lever 165 in engagement with the cam 12, which affords the means for operating the levers 165 at the proper time. The

blades 163 register in substantially. the same vertical plane with the outer face of the bottom 34, which is held in engagement with the end of` block B, while the block is near the mandrel, as hereinabove described, and normally occupy the positions depicted in Fig. 1a

After the ejecting plates 124 have ejected the folded blank with its wrapper from the mandrel M and shifted same so as to embrace the bottom 34 and the'block B, and the ejecting plates havelretracted to leave osition, the cam 12 presses therarm 170 o the lower lever 1651upwardly'and thereby raises the lower blade 163, while said .lower lever, through the instrumentality of its arm 174 and arm 171 of the upper lever 165, causes the arm 167 of said upper lever to descend and lower the upper blade 163 simultaneously therewith, with the result that said blades 163 engage' the projecting edge of the adhesive wrapper at'the ends of the folded blank and not only fold same over the edge of the end walls of the folded blank, but, also, press same flat] into engagement with the outer face of t e bottom 34, 'whereby same adheres to said bottom. Simultaneously with the completion of pressing the projecting edge of the adhesive wrapper Hatly against tlfie outer face of the bot-tom 34 at the ends o just described, the cam-15, through the intermediation of roller 156, member 154, and bar 152, causes the block B to lmove the fo-lded blank 30 and its bottom 34 away from as to move the bottom 34 immediately out of engagement with the folding blades 163, after which the cam 12 permits the pull of spring 175 to return the blades 163 to their initial position. By this the latter by the folding blade 163 as arrangement the adhesive wrapper 61 is v moved out of engagement with the blades 163 before same has a chance to adhere to the latter,'in case any of the adhesive material accidentally runsup-on said blades.

After the cam 15 causes the block B to` move away from the mandrel M, z'. e., toward the right, Figs. 1 and 2, through the lintermediation of roller 156, member 154, and bar 152, the roller 156 rides upon the surmesses face 176 of said cam and thereby holds the block Bin such position that the outer face of the bottom 34 registers in the same verticalplane with the folding blades 164, during which time said blades are actuated so as to fold the projecting edge of the adhesive wrapper at the sides of the. folded blank against the outer face of the bottom 34 of the box in the manner now to be described.

The folding blades 164 are secured to the levers 177, respectively, by any suitable means, each of which levers is preferably in the form of a bell-crank. One of--the levers 17 7- isl rigidly mounted on a shaft 178 journaled in a support 179, which is mounted on the main frame 1, so that its bladesupporting arm 180` extends behind the block B, and the other lever 177 is rigidly mounted on Aa shaft 181 which is journaled in a support 182 so that its blade-supporting arm 183V extends infront of the block B, said support 182 being mounted on the main frame 1. The arm 184 of the front lever 177 contains a notch 185 in the end thereof to receive a gear tooth or projection 186 borne by the end of arm 187 of the rear lever 177, and by this arrangement, when one lever 177 is rocked, same causes the other lever 17 7 to rock simultaneously therewith, but inthe opposite direction therefrom. An arm 188 borne by the shaft 181 has a roller 189 rotatably attached at 190`thereto, said roller being held in engagement with the cam 14 by means of a spring 191, which cam affords the means for actuating the folding blades 164 at the proper time. The bladeSk 164 normally occupy the position depicted in Fig. 14, but while the roller rides upon the surface 176 of cam 15 and thereby holds the block B in such position that the outer 4face of the bottom 34, which has been partly connected 4to the folded blank upon said block ashereinabove described, registers in substantially the same plane with the folding blades 164, the cam 14 `permits the spring 199 to pull the arm 188 borne b shaft 181 rearwardly, thus causing the sha t 181 to rock the forward lever 177 counterclockwise, Fig. 14, whereby the arm 183 of said forward lever movesthe forwardl fold-l ing blade rearwardly toward the block B,

, While said forward lever, through the instrumentality of itsv arm 184'and the arm 187 of the rear .lever 17 7, causes the arm 180 of said rear lever to move the rear folding -blade 164 forwardly toward the block B simultaneously therewith, with the result that said folding blades 164 engage the projecting edge of the adhesive y wrapper at the sides of the folded blank and not only fold same over the edge of the end walls of th'e folded blank, but, also, press same flatly into engagement with the outer face of the bottom 34, whereby same adheres to said bottom. .This operation completes the formation of the box, ywhich `is depicted in Figs. 26 and 27, whereupon the cam 15 immediately cau-ses the block B to move the completed box farther away from the mandrel M, in order to prevent the adhesive wrapper from adhering to the folding blades'164, in caseany of the adhesive material accidentally runs upon the folding blades 164, and, also, to eject the completed box from the machine in the manner hereinafter described.

In order to adord a means for positively sition upon the block B and, also, to insure against accidental ejectment of the folded blank from the block B, while the edge of the adhesive wrapper is being folded against the outer/ face of the bottom 34 to complete the formation of the box, al pair of-plates 192' anda plate 193 are provided. AThe plates 192 are arranged so as to press against the side faces of the block B where the sides of the folded blank embrace same adjacent the end face thereof and arehinged to the plates 194, respectivel which plates 194 are secured to the bloc B by screws 195 or other suitable means. In like manvholding the folded blank in its proper po- Y,

ner the plate 193 is arranged so as to press Y against the lower face of the block B where the end of the folded blank embraces same adjacent the end face thereof and ishinged toa plate 196 which is secured to the block B by screws 197 or other suitable means. Said plates 192 are held in pressing engagement with the side faces of the block B by a spring 198er a plurality of such springs, said spring or springs being arranged to press against extensions 199 borne by said plates 192, respectively, and being held in place by screws 200, which are attached to said extensions. A spring 201 is arranged to press against the extension 202 borne by plate 193 so as to hold the latter in pressing engagement with the lower face of the block B and is held in place by a screw 208 which is attached to said extension 202. The edges of the plates 192 and 193 that are adjacent the end face of the block B are preferably bent so as to flare outwardly from 'the block B, in order to allow the folded blank to' slide readily upon said block. When the folded blank is ejected from the mandrel M- `of the block B and the flared edge of the plate 193 with the. result that the pressure of springs 198 and 201 cause the plates 192 and 193 to hold the sides and th. lower end of the folded blank in engagement with the side and. lower faces, respectively, of the
